Briz — Simplifying Invoicing & Daily Tasks

1. Overview

• Product: Mobile business management and invoicing application for micro-enterprises and independent shop owners.
• Audience: Small retail merchants, freelancers, and independent contractors in emerging markets operating predominantly on smartphones.
• Role: Product Designer at Bytecare Technology, leading user research, user journey mapping, and mobile UI flows.
• Timeline & Context: 4-month iterative design cycle aimed at improving mobile invoice creation and receivables tracking.

2. Problem

Small shop owners struggled to create professional invoices on mobile devices while serving walk-in customers:

• Existing desktop-first accounting tools required too many inputs (tax category codes, warehouse IDs, payment terms), causing shop owners to revert to handwritten paper receipts.
• Handwritten receipts led to lost revenue, forgotten payments, and hours spent recalculating balances at the end of each month.
• Users lacked immediate feedback on whether a digital receipt had been successfully viewed or acknowledged by their customer.

3. Evidence and Constraints

• Field Interviews: Spoke with 12 local business owners in Nepal; 9 reported that creating a digital invoice felt "too slow to do while a customer was standing in front of the counter."
• Device Limitations: Target users operated on budget Android devices with smaller screens (5.5" to 6.2") and intermittent mobile network connectivity.
• Cognitive Constraints: Financial terminology (e.g., "accounts receivable aging", "ledger debits") created intimidation. The interface had to use clear, everyday language ("Money In", "Money Out", "Unpaid Bills").

4. Decisions and Trade-offs

1. Linear Stepper vs. Single Scrollable Form:
   • Option A: One long scrollable form with all 14 fields.
   • Option B: Three-step progressive flow: Customer -> Line Items -> Instant Share.
   • Decision: We implemented Option B. Breaking the task into bite-sized screens reduced visual anxiety and allowed auto-advancing as soon as an item was added.
2. Pre-populated Catalog vs. Freeform Typing:
   • Allowed merchants to tap frequent inventory items from a horizontal quick-select strip rather than typing item descriptions and prices manually each time.
3. Direct WhatsApp & SMS Sharing:
   • Instead of requiring email addresses (which most local retail buyers do not use regularly), we placed one-tap WhatsApp and SMS PDF sharing at the completion of every sale.

5. Solution

• Three-Step Quick Invoice Flow: Select customer -> Tap item -> Confirm total. Creation time dropped to under 30 seconds.
• Everyday Financial Language: Simplified complex accounting terms into clear, visual transaction summaries with distinct color-coded badges for "Paid" and "Due".
• One-Tap Payment Reminders: Friendly, pre-formatted payment reminder messages that owners can send to clients directly over messaging apps without feeling confrontational.
• Offline-First Local Drafting: Invoices save instantly to the local device even during mobile internet drops, syncing automatically when connectivity returns.

6. Outcome and Learnings

• What Was Delivered: Complete end-to-end mobile design specifications, component library, and interactive prototypes tested with local merchants.
• Verified Results: Merchants using the simplified three-step flow completed invoice generation in an average of 28 seconds (down from over 2 minutes in earlier versions).
• What Remains to Be Validated: Long-term merchant retention on automated monthly tax summary exports across varying retail verticals.
• Key Takeaway: In mobile product design for non-technical users, clarity beats feature density every single time. Removing three non-essential fields did more for user adoption than any advanced feature could.
